INTERNAL-COMBUSTION MOTOR.

Application filed November To all whom it may concern Be it known that we, .\XEL ERIK HAGDERG and JOHAX E. Pitnssox, both subjects of the King of Sweden. and residents of Milwaukee. in the county of Milwaukee and State of \Visconsin, have invented new and useful Improvements in Internal-Combustion Motors, of which the following is a full, clear, and exact description.

This invention relates to internal combustion motors.

The general object of this invention is the provision of a simple and efficient internal combustion motor provided with means for utilizing power created by the explodin of explosive mixtures without using cylin ers, pistons and cranks.

This object is accom lished by providing a casing in which a p urality of explosion chambers are formed, locating in the explosion chambers means for compressing the explosive charges, associating. with the casing a turbine wheel which is fixed to a shaft rotatably mounted in the casing, forming in the end of the casing passages which convey the products of combustion from the explosion chambers to the turbine wheel. mounting on the casing means for controlling the flow of the products of combustion through the passages. and providing means driven from the turbine wheel shaft for operating the means for controlling the flow of the products of combustion and the means for compressing the explosive charges.

This and other objects of the invention will be more clearly understood from the following detailed description and accompanying drawings.

ed to a position between the openings in tlo casing wall.

Referring to the above-mentioned figures, the invention includes a cylindrical casing 10 provided with a plurality of walls 11 extending radially inward. *ormed in opposite ends of the cylindrical casing are openings 1; and 13. Encircling the opening 13 and extending parallel to the cylindrical casing is a rim 1-1 provided with an external thread at its outer end. Rotatably mounted on the rim 14 and abutting against the end of the cylindrical casing 10 is an annular plate 1.3 having attached to its lower edge a yoke 16 in the ends of which two pulleys 1T and 18 are rotatably mounted. A hollow annular block 19 having an annular slot 20 cut in its inner face is mounted on the rim 14. the rim fitting into the annular slot and its external thread engaging with a thread provided on the metal defining the outer edge of the annular slot .20. Attached to the annular block 19 by means of screw bolts 1% is a turbine casing 24. A shaft 29 having one end rotatably mounted in the frame 30 extends through the casing 10, the annular block 19 in which it is journaled, and into the turbine casing 21. Fixed to the end of the shaft 29 by means of the key 26 is a turbine wheel '25. collar 27 is also mounted on the end of the shaft '39 to retain the turbine wheel in position. plurality of openings .12 are formed in one end of the cylindrical casing 10. one opening being located on each side of each wall 11. These openings arecadjacent to the walls 11 and to the outer wall of the casing 10. A plurality of openings 2 are formed in the plate 15. The number of these openings 23 will be determined by the number of openings 22 in the end of the cylindrical casing 10. In this case the number of openings 23 is equal t one-half the number of the openings 2; in the end of the casing. The openings .23 are evenly spaced about the plate 15 and when the plate stands in its central position each opening 23 is located midway between a pair of openings- 222 formed in the end of the casing 10 as shown in Figure 7. Passages 21 are vided iu the outer l'llll of the 1101- low annular block if) in ulineiucnt with the openings 2; in the end of the asing. These passages are shaped like a nozzle and arc located HI aline nem with the blades of the turbine wheel '23.

llo

Extending throu h the outer wall of the casing 10 are a p urality of openings 33, one of which is located on each side of each wall 11 thus positioning two openings 33 between any two of the walls 11. One-way valves 34 are mounted in the openings 33 for controlling the flow of an explosive mixture through the openings. Pipe lines 35 leading from carburetors 36 communicate with each of the openings 33 for conveying the explosive mixture to the casing 10. plurality of spark plugs 37 are mounted in the ends of the casing for firing the explosive mixture conveyed into the casing by means of the pipes 35. A spark plug is provided for each opening 33.

Rotatably mounted on the shaft 29 is a rotor including a cylindrical member 31 and a plurality of walls 32 extending radially outward. The number of walls 32 provided is equal in number to the number of walls 11 carried by the casing 10. A rotor wall 32 is located in each space between the walls 11 of the casing. A yoke 38, the arms of which carry two wheels 39 and 40, is formed integral with the cylindrical member 31. The cylindrical member 31 in conjunction with the casing 10 and the casing walls 11 forms a plurality of combustion chambers 41.

A shaft 42 is rotatably mounted in the frame 30 and the cylindrical casing 10. Fixed to the inner end of the sl|aft42 is a cam 43 mounted in alinement with the yoke 38 and between the wheels 39 arid carried by the arms of the yoke. Two other gears 44 and 45 are fixed to the shaft 42, the gear 44"mcshing with a pinion 4G fixed lo the shaft 29. A shaft 47 rotatably mounted in the frame 30 carries a gear 48 meshing with the gear 45. Fixed to the shaft 47 is a cam 49 located between the arms of the yoke 15. A squared end .W is formed on the end of the shaft 47 so that the shaft may be engaged by a crank or other means for rotating it.

The operation of this internal combustion motor is as follows:

By means of a crank or other device attached to the squared end of the shaft 47 the latter is rotated. A cam 49 fixed to the shaft 47 rocks or oscillates the plate 15. Tho rotor is oscillated or rocked about the shaft 29 by the cam 43 which is operated from the shaft 47 through gears 48 and 45 and the shaft 42. Considering Figure 2. when the motor is set in operation by rotating the shaft 47 the openings 29 in the end of the casing are all closed by the plate 17 The rotor operated through the ram 4:; begins to more counter lockwise, com pre-sing the air located in the front of the wings 3*. and reducing the atmospheric presslll'e behind thc wing :12 in the chambers 41. \Vhcn thc atmospheric pres ure in the chambers 41 has been reduced explosive charges are fed into the combustion chambers 41 through the pipe lines 35 and the one-way valves 34. After the rotor has completed its counterclockwise movement it comes to a standstill and for a moment is in astationary position. The plate 15 is shifted and the openings 23 are alined with the openings 22 in the end of the casing adjacent and in a clockwise direction from the walls 11. The compressed air in front of the rotor walls 32 escapes into the turbine casing 24 and impinges on the blades of the turbine wheel 23 rotating the shaft 47. At the same instant as the rotor begins its clockwise movement the plate 15 shifts, closing the openings 22 adjacent the walls 11 and in a clockwise direction from them. As the rotor moves clockwise, the charges located in the combustion chambers in front of the rotor walls 32 are compressed and fresh charges are fed into the combustion chambers 41 in the rear of the rotor walls 32. When the rotor has completed its clockwise movement and for a moment is in a stationary or what we term the dwell position, the compressed charges are fired. At the same instant as the firing of the charges the plate 15 shifts, alining the openings 23 in the plate 15 with the openings 22 adjacent the walls 11 and in a counterclockwise direction from them. This allows the gases generated by the firing of the charges to escape into the turbine casing 24 to impinge on the blades of the turbine wheel 25. operating the latter. Now the turbine wheel by means of the shaft 29, pinion 46, gear 44 and the cam 43 operates the rotor, rocking it counterclockwise. At the same instant as the rotor begins its counterclockwise movement the plate 17 shifts. closing theopenings 22 adjacent the walls 11 and in a counterclockwise direction from them. As the rotor moves counterclockwise the charges located in the combustion chambers in front of the rotor walls 32 are compressed and fresh charges are fed into the combustion chambers 41 .in the rear of the rotor walls 32. When the rotor has completed its counterclockwise movement and for a moment is in a stationary or dwell position the second compressed charges are fired. At the same instant as the firing of the charges the plate 15 shifts, alining the openings 23 in the plate 15 with the openings 22 adjacent the walls 11 and in a clockwise direction from them. This allows the gases generated by the firing of the charges to escape into the turbine casing 24 to impinge on the blades of the turbine wheel A series of operations similar to the ones described above ooninue. First, the rotor is 0 rated through the cam 43 and compresses t e charges located in front of it as it moves and reducing the pressure behind it ill to allow new charges to be fed into the comhustion chambers. The rotor is now in a stationary or dwell position, the compressed charges are tired and the cam 49 operates the plate 15 to open the passages in front of the walls 32 into the turbine chamber, allowing the gases generated by the tiring of the charges to operate the turbine. The rotor changes its direction. the plate 15 shifts, closing the passages into the turbine chamber. The rotor as it now moves compresses the charges located in front of it and reduces the prts ure behind it to allow new charges to be fed into the combustion chamhers. .\gain the rotor is in a stationary or dwell position. the compressed charges are tired. the plate to opens the passages in front of the walls 32 into the turbine chamber. allowing the gases gtuierated by the firing of the charges to operate the turbine. Again the rotor changes its direction. This continuous series of operations operates the turbine wheel and the shaft 2!) from which power may be transmitted by any transmission system.

\\'c would state in conclusion that while the illustrated example con titutes a practical embodiment of our invention we do not limit ourselves strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as delined in the appended claims.
